The Ancient Mayan People have described the cycles of both the universe and nature around us. They created a harmonic calendar that is synchronized to all those cycles.

The Tzolkin and 13 Moon Calendar is therefore less of a human invention, and more of a profound insight into the organizational tendencies within nature. Mayan cosmology developed this insight with great ingenuity and sophistication.

Our Gregorian calendar is not synchronized to the natural cycles and thus not aware. The Mayan Calendar is one of the tools you can use to make you more conscious. It can help you get a stronger connection with the cycles of this cosmic organization of time. And you can learn to anticipate the energies that influence everyone in daily life, every sun, every moon, every day.

All this is explained carefully in more than 15.000 words and 37 pages!

In the New Time, synchronicity is the norm.

"13:20:Sync makes it so much easier to understand and integrate the calendar into every day life. Highly recommend it."

For the beginner this app is a learning tool because it contains a lot of information about Tones and Seals and the synchronizing order. You may think it's difficult at first but soon you will feel how it all connects and how the cycles of the Mayan Calendar work.

"This app is great, and allows easy manipulation of dates. I spent years in books doing in hours what I can now do in seconds."

For the ones who are already familiar with the Mayan Calendar this app is a handy tool to navigate through the days, and calculate the Combined Kin for any given combination.
This app can be of great assistance to teach other people about the 13:20 cycles.

Tell me, and I will forget.
Show me, and I may remember.
Involve me, and I will understand.
